I am needing help with the following six puzzles. Any and all help would be greatly appreciated.

1. Here is a long division sum, showing all the work, and the result. Simple, right? The sum works out exactly, with no remainder. The slight complication is, that all the numbers have been replaced with letters on a random basis. However, one letter always represents the same number. Can you reconstruct the original sum?

3. Can you figure out the reasoning of these numbers, and replace the question mark with the correct number?

5 3 8 7
12 15 49 56
3 9 4 12
18 27 36 ?

4.Take a look at these digital "watches". By cracking the logic that connects them, you should be able to figure out what time should be on watch number five.

15.14.01
12.18.00
08.26.58
03.42.55
??.??.??

5.Thirty-six

Sixty-four

Seventy-two

Twenty-five

Eighty-one

What is the odd number out?

6. Can you figure out the logic behind these number "squares" and find the number that replaces the question mark?

9 6 5 10 4 6 ? 5
4 2 3 7 8 11 12 7

(Think of each set of four numbers as a square. 9 = top left, 4 = bottom left, 6 = top right, 2 = bottom right, and so on, it might help to write them down.)

Thank you again for any and all help

Hello, mathguy9!

I hope I interpreted #1 correctly . . .

Question really means: which number does not belong ?
Easy...LOOK carefully!

The answer is 48. The numbers are in four squares of four numbers, so the first square is:
